Hi, same problem here. i have Win 7 x64 AMD CPU and Omnia 7 on mi7ROM (fully unlocked). I deployed the XAP no problemo. i connected the phone, started the app and says 'OK' on all items except for CoreConno IPs: No IPs. And the most curious thing was that Win7 didn't recognise any new devices. I have to point out, though, that I couldn't install MAGLDR on Windows 7, and tried to install the WMDC while my phone WASN'T plugged in and it installedf but nothing new happened. I managed to install the MAGLDR when I plugged my Omnia 7, and THEN started the WMDC install exe (in my case 'drvupdate-amd64.exe') and only then did it recognise the "new" device and installed the necessary drivers to recognise my phone in storage mode. then I had to to the same when I plugged my phone in MAGDLR mode (again, I had to start the WMDC install, and only then it recognised my phone in MAGDLR mode and installed the necessary drivers, really weird). And now I have a flashed phone, works O.K. but when I tried this WMCD launcher app, nothing happens. Sooo, I plugged my phone with the app off, started Zune and then started the app. the app seems to be working fine but nothing happened on my PC so I started the WMDC install exe again, and it said that Windows 7 recognized a new device, installing the drivers, but then it says "Device unplugged" and no drivers are installed. i tried the same procedure with Zune on. i dunno what to do. I have windows phone power tools and it works but this method seems to elude me somehow. Any solution? PLS help
